Function DescriptionThe safety relay PPNOZ X2.8P provides a safety-oriented interruption of a safety circuit.When supply voltage is supplied the "POWER" LED is lit. The unit is ready for operationwhen the start circuit S12-S34 is closed.} Input circuit is closed (e.g. E-STOP pushbutton not operated):
– LEDs "CH1" and "CH2" will light.
– Safety contacts 13-14, 23-24 and 33-34 are closed, auxiliary contact 41-42 is open.The unit is active.
} Input circuit is opened (e.g. E-STOP pushbutton operated):
– The LEDs "CH1" and "CH2" go out.
– Safety contacts 13-14, 23-24 and 33-34 are opened redundantly, auxiliary contact41-42 is closed.
Operating modes} Single-channel operation: No redundancy in the input circuit, earth faults in the start and
input circuit are detected.} Dual-channel operation without detection of shorts across contacts: Redundant input cir-
cuit, detects PNOZ X2.8P
– earth faults in the start and input circuit,
– short circuits in the input circuit.} Dual-channel operation with detection of shorts across contacts: Redundant input circuit,
PNOZ X2.8P detects
– earth faults in the start and input circuit,
– short circuits in the input circuit,
– shorts across contacts in the input circuit.} Automatic start: Unit is active once the input circuit has been closed.} Manual start: Unit is active once the input circuit and the start circuit are closed.} Increase in the number of available contacts by connecting contact expandsion modules
or external contactors/relays.

WiringPlease note:
} Information given in the "Technical details [ 17]" must be followed.} Outputs 13-14, 23-24, 33-34 are safety contacts; output 41-42 is an auxiliary contact (e.g.
for display).} Auxiliary contact 41-42 should not be used for safety circuits!} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 17]).} Calculation of the max. cable length lmax in the input circuit:
Rlmax
Rl / km
Imax
=
Rlmax = max. overall cable resistance (see Technical details [ 17])Rl / km = cable resistance/km
} Use copper wiring with a temperature stability of 60/75 °C.} To prevent EMC interferences (particularly common-mode interferences) the measures
described in EN 60204-1 must be executed. This includes the separate routing of cablesof the control circuits (input, start and feedback loop) from other cables for energy trans-mission or the shielding of cables, for example.
} Adequate protection must be provided on all output contacts with capacitive and inductiveloads.
} Do not switch low currents using contacts that have been used previously with high cur-rents.
} When connecting magnetically operated, reed proximity switches, ensure that the max.peak inrush current (on the input circuit) does not overload the proximity switch.
} With 24 V AC/DC units:The power supply must meet the regulations for extra low voltages with protective elec-trical separation (SELV, PELV).
Important for detection of shorts across contacts:
As this function for detecting shorts across contacts is not failsafe, it is tested by Pilz duringthe final control check. If there is a danger of exceeding the cable runs, we recommend thefollowing test after the installation of the device:
1. Unit ready for operation (output contacts closed)
2. Short circuit the test terminals S12, S22 for detecting shorts across the inputs.
3. The unit's fuse must be triggered and the output contacts must open. Cable lengths inthe scale of the maximum length can delay the fuse triggering for up to 2 minutes.
4. Reset the fuse: remove the short circuit and switch off the supply voltage for approx. 1minute.

NOTICE
With single-channel wiring the safety level of your machine/plant may belower than the safety level of the unit (see Safety characteristicdata [ 27]).
NOTICEOperation with a light guard or safety switch
It must not be possible to switch off the supply voltage for the PNOZ X2.8Pseparately from the supply voltage for the light guard or safety switch.

OperationWhen the relay outputs are switched on, the mechanical contact on the relay cannot betested automatically. Depending on the operational environment, measures to detect thenon-opening of switching elements may be required under some circumstances.
When the product is used in accordance with the European Machinery Directive, a checkmust be carried out to ensure that the safety contacts on the relay outputs open correctly.Open the safety contacts (switch off output) and start the device again, so that the internaldiagnostics can check that the safety contacts open correctly} for SIL CL 3/PL e at least 1x per month} for SIL CL 2/PL d at least 1x per year
NOTICE
The safety function should be checked after initial commissioning and eachtime the plant/machine is changed. The safety functions may only bechecked by qualified personnel.

Explanatory notes for the safety-related characteristic data:} The SIL CL value in accordance with EN 62061 corresponds to the SIL value in accord-
ance with EN 61508.} TM is the maximum mission time in accordance with EN ISO 13849-1. The value also ap-
plies as the retest interval in accordance with EN 61508-6 and IEC 61511 and as theproof test interval and mission time in accordance with EN 62061.
All the units used within a safety function must be considered when calculating the safetycharacteristic data.
INFORMATION
A safety function's SIL/PL values are not identical to the SIL/PL values ofthe units that are used and may be different. We recommend that you usethe PAScal software tool to calculate the safety function's SIL/PL values.
Supplementary data
CAUTION!
It is essential to consider the relay's service life graphs. The relay outputs'safety-related characteristic data is only valid if the values in the service lifegraphs are met.
The PFH value depends on the switch frequency and the load of the relay output.If the service life graphs are not accessible, the stated PFH value can be used irrespectiveof the switch frequency and the load, as the PFH value already considers the relay's B10dvalue as well as the failure rates of the other components.

Service life graphThe service life graphs indicate the number of cycles from which failures due to wear mustbe expected. The wear is mainly caused by the electrical load; the mechanical load is negli-gible.

Example} Inductive load: 0.2 A} Utilisation category: AC15} Contact service life: 2 000 000 cycles
Provided the application to be implemented requires fewer than 2 000 000 cycles, the PFHvalue (see Technical details [ 17]) can be used in the calculation.
To increase the service life, sufficient spark suppression must be provided on all outputcontacts. With capacitive loads, any power surges that occur must be noted. With DC con-tactors, use flywheel diodes for spark suppression.
